The electrocatalytic activity of the electrode forhydrogen evolution reaction(HGR) in alkaline solution was studied. Cathodicpolarization curves showed the electrocatalytic activity of Ni/C electrode prepared byMVS method was higher than that of the one prepared by conventional method.展开更多

X-ray photoelectron spectroscopy (XPS) investigations indicated that the copper in all the samples was in a metallic state. XRD measurements showed that the mean diameters of Cu particles prepared by SMAI were small. Catalytical tests showed that the SMAI catalyst had high CO oxidation activity.展开更多
Two new carbonyl manganese compounds were obtained by reactions of 2.6-di(biphenylphosphine) pyridine (PNP) with CpMn(CO)(3).

The structures of the compounds were confirmed by elemental analysis, IR, H-1 NMR and P-31 NMR. The results showed that the mixed-donor ligand (PNP) was coordinated to manganese only through the phosphorus atom.展开更多
